The M8 3-pin connector and IP67 rating mean it's ready for direct mounting on pneumatic actuators or linear slides in washdown zones — no extra enclosure needed. The 200 mA switching capacity covers most solenoid valves and indicator loads directly, so you can skip an interposing relay on small valves. The 10…30 V DC input gives you headroom on a 24 V nominal bus — no regulator needed for a 12 V line. Zinc die-cast housing stands up to mechanical abuse on a cylinder end-cap, and the -25…70 °C range keeps it working in unheated factory bays or near oven stations. The magneto-resistive sensing principle gives a clean digital on/off without contact bounce — no debounce delay in the PLC scan. The yellow LED on the body gives an instant visual check during commissioning or line-down troubleshooting. ## Mounting and wiring note The 15.5 x 14 x 34 mm body fits standard T-slot actuator grooves. The M8 3-pin connector mates with a standard M8 cordset — no special tooling needed. PNP output means the load connects between the output and 0 V; verify your PLC input card is sinking before wiring.","metaTitle":"Festo SMTO-1-PS-S-LED-24-B Proximity Sensor, PNP, M8, IP67","metaDescription":"Festo SMTO-1-PS-S-LED-24-B proximity sensor, PNP normally open, 10-30 V DC, 200 mA, M8 3-pin, IP67, magneto-resistive, LED.
